l This invention relates to pumps of the reciprocatory plunger type, and has for its objects to produce a comparatively simple inexpensivedevice of this character in which a pair of plungers will be simultaneously actuated by a single handle and one wherein the plungers will be maintained in proper position within and guided in their movements through the pump-barrel or stand-pipe.

A further object of the invention is to provide simple and eHicient connections between theplunger rods and handle and means for balancing the latter to insure a steady even movement of the parts and minimize the power necessary for operating the, pump.

`With these and other objects in view the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a side elevation, partly in section, of a pump embodying the invention. Fig. 2 is a vertical longitudinal section, on .an enlarged scale, taken on the line 2 2 ofFig. 1. Fig. 3 is a detail elevation of the upperportion of the plunger-rods and their bearing members.

Fig. 4 is a plan view of the parts shown in Fig. 3.

Referring to the drawings, 1 designates a tubular pump-barrel or stand-pipe provided with a discharge-nozzle 2 and having secured upon its upp'er end a vertical guide member or extension 3, provided with oppostely-disposed guide ways or slots 4 and at its upper end with bearings 5, which receive a horizontal bolt or axle 6, upon which is pivoted an operating-handle 7, these parts ,being all of the usual or any appropriatematerial.

Arranged for reciprocation within the barrel 1 is a primary upper plunger or bucket 8, carried'by and attached to the lower end of a primary tubular plunger-rod 9,I through which extends for reciprocation a secondary plunger-rod 10, carrying atits lower end a secondary plunger head orbucket 1 1, the rod 10 being of somewhat-greater length than the rod 9 and adapted inpractice to project a suitable distance beyond the'upper and lower ends of the latter.

Frans, OF'REDKEY, INDIANA-Assieme or ONE-HALF To f ALBERT w. K'EHRER, or REDKEY, INDIANA.

Fixed Iupon the upper end ofthe primary plunger-rod 9 is a bearing member or head 12 provided with laterally-projecting body portions or flanges 13 adapted to fit movably between the guide ways or slots 4, there being formed upon the head 12 to project at right angles to the flanges 13 a horizontallyprojecting perforated ear 14, while upon the upper end of the secondary rod 10 is fixed a similar bearing member or head 15, provided with guide portions or flanges 16, which likewise enter-the guideways 4, and with a projecting'vertically-depending member or ear 17, perforated at its lower end.

Pivotally connected at their upper ends to 'the handle 7 and at opposite sides of the eX- tension 3 is a pair of coupling members or links 18 19, the lower ends of which are pivotally connected in turnwith the ears 14 17,

respectively, thus coupling the rods 9 and 10 to and for movement with the handle 7, upon the forward end of which latter is -Xed a counterbalancing-weight 20.

In practice as the handle 7 is operated in the usual manner the plungers 9 and 1() will through the medium of their connections 18 and 19 be simultaneously reci rocated in relatively reverse directions, t us causing the plungers 8 and 11 upon one stroke of the handle to operate and upon the other stroke to recede from each other, or, in other words, imparting to the plungers a relatively. reverse reciprocation, through the medium of which a continuous flow of water ismaintained. It will be observed in this connection that lateral movement or tipp'ing of the plungers during operation is obviated, owing to the heads 15 beingguided in their movements longitudinally of the guide extension 3,

and,further, that owing tothe member -17 being extended downward from its head 15 the heads 13 and 15 may be spaced wider apart for obtaining a greater throw or stroke of the plungers comparative with the length of the links' 18 19 and height of the eXtension 3. It will also be noted that by weighting the outer end of the handle 7 the latter is nicely balanced, thus insuring perfect operation anda minimization of the power necessary for operating the pump.

From the foregoing it is apparent that I ends of the rods and provided with verticallyw disposed radially-projecting guide -iianges7 said heads being each provided with a perforated ear projecting in a radial line at right angles to the flanges, a vertical extension carried by the upper end of the pump and comd pl'ising relatively spaced side plates provided with longitudinal guide-'slots designed to rcceive the guide-flanges, an operating-handle pivoted to the up er end ofthe extension between the side p ates, and links pivoted respectively to the ears and pivotally connected with the handle.

In testimony whereof I aiiix my signature in presence of' two witnesses.

WILLIAM T. FIERS.
